JAMES REILLY, OF NEW YORK, N. Y.

. CASING FOR STEAM-PIPES, 800.

SPECIFICATION forming part of Letters Patent No. 282,368, dated July 31, 18853.

Application filed March 22, 1883. (No model.)

'To all whom it may concern.-

for steam and other heating agents, the object of the casing being to prevent condensation or the cooling of the agent from the action of the air upon the pipe or conduit.

The invention consists, essentially, in the construction of the joint formed at the edges of the material of which the casing is composed when the same are brought together, the object being to provide a convenient method of applying the casing and securing it in position in such manner that it may be efiectually secured, and at the same time may be readily removed or opened for examination when necessary. The details of the invention and its method of operation will be understood from the description hereinafter presented, reference being had to the accompanying drawings, in which- Figure 1 is a view of the casing with its edges separated. Fig. 2 is a vertical section of Fig."1 through the central apertures, d. Fig. 3 is a vertical section, and Fig. 4 is a side view, showing the casing closed. Fig. 5 is a detached view of a portion of the .lip a, showing the block 6. v

A denotes the casing, which will usually be cylindrical in form, and is composed of sheet metal or other approved material, and which in respect of its general construction and operation, with the. exception of my improved joint, does not differ essentially from the cas ings now in use. The joint' is formed by at:

taching a supplemental piece or lip, a, upon the interior surface of one side-of the casing, so as to form a pocket to receive the other side, 0, of thecasing, as indicated in Fig. 1. The lip or projecting piece a is secured at one end by rivets or otherwise back from the edge of l.

supplemental piece a, the apertures or series of apertures d are formed, the aperture in the side 0 being arranged to come directlybetween the apertures in the side B and supplemental piece awhen the sides of the casing'are brought together, and when the apertures are in this position the joints may be effectually secured;

by passing a screw, m, through them. The supplemental piece a has. attached to its under side, below theaperture (Z, the blocks e, having threaded apertures f, corresponding with the apertures in the piece a, the blocks constituting, when in position, fixed nuts for the screws ml The preferred form of the blocks a is illustrated in Fig. 5, and in the present instance the blocks are secured to the lip a by rivets passing through the ears :0 w. The casingwill be made'in sections of any desired length, the ends of the sections being slipped one in the other, and there secured by the screws m, which are adjacent to the ends of the sections. When the casing is to consist of sections connected as described, the lip a will not extend quite to the end of the section which is to receive the end of the adjoining section, as indicated in Fig. 1, and hence when the end of the section lettered H is inserted in the end of the section I it will strike the edge of the lip a, and

the apertures d will come opposite to each other 7 and receive the screw on. The internal pressfact that it is neat in appearance and will permit of an inspection of the interior of the casing are advantages which should not be overlooked.

It is apparent that, if desired, the parts eonstituting the joint may be made in the nature of an attachment andattached to the casing in any convenient way. I do not therefore limit myself to the exact construction which I have described; but

What I claim as my invention, and desire to secure by Letters Patent, is'- 1. The steam-pipe casing having 011 one of its sides the supplemental piece, forming a pocket to receive the other side thereof, and carrying the internally-threaded blocks, the casing and supplemental piece having apertures in line with the blocks to permit of the 15 joint being secured byserews, substantially as set forth.

presence of two witnesses.
